4N36SR2VM

Transistor, Photovoltaic Output Optoisolators Overview

The 4N36SR2VM is a general-purpose, single-channel optoisolator manufactured by onsemi (formerly Fairchild Semiconductor). It features a phototransistor output with an accessible base terminal and provides 4170Vrms isolation voltage. The device operates within a temperature range of -40°C to 100°C and utilizes a 6-SMD Gull Wing surface-mount package. Key electrical parameters include a maximum DC forward current of 60 mA, a typical forward voltage of 1.18 V, and a minimum current transfer ratio of 100% at 10 mA input. The output transistor supports a maximum collector-emitter voltage of 30 V with a saturation voltage of 300 mV. Typical switching times are 2 µs for both turn-on and turn-off.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

This component is officially classified as obsolete and no longer manufactured by onsemi. Procurement should focus on verified direct substitutes such as the 4N36SR2M from the same manufacturer. Buyers must confirm availability through authorized distributors and verify that replacement parts meet the original pinout and electrical specifications. Due to the end-of-life status, long-term supply chain stability requires careful evaluation of alternative sources.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a standard phototransistor optocoupler with a base terminal is required for basic isolation tasks. The 4170Vrms rating suits applications needing robust noise immunity. Consider the 6-SMD package for automated surface-mount production. Verify that the 100% CTR at 10mA meets the drive requirements of the downstream circuitry. Ensure the operating temperature range aligns with the environmental conditions of the final assembly.

Transistor, Photovoltaic Output Optoisolators Part Context

The 4N36 series represents a widely used family of general-purpose optoisolators originally developed by Fairchild Semiconductor. The SR2 suffix typically denotes specific tape-and-reel packaging and compliance variations. This part belongs to the broader category of transistor-output optocouplers, which are fundamental components for electrical isolation in digital and analog signal transmission. The transition from Fairchild to onsemi maintains the legacy specifications while updating manufacturing standards.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The 4N36SR2M is listed as a direct substitute by onsemi. Verify pin compatibility and electrical ratings before integration. Other similar options exist but may require schematic adjustments.
